US spot bitcoin ETFs lost $681 million in net outflows in the week of 5 to 9 October 2026, their largest weekly withdrawal since June, according to SoSoValue data cited by CoinDesk. Most of the money left on Wednesday and Thursday, as rising oil prices revived inflation worries and bitcoin slipped. Flows turned positive again on Tuesday 13 October, when the funds drew $175.6 million.
Bitcoin ETF outflows: the numbers
The week’s selling was concentrated in two sessions. Crypto Briefing reports net outflows of $487 million on 7 October and $244 million on 8 October. Data providers differ slightly on the weekly total: TokenPost put it at $678.9 million. The week ended a three-week run of inflows.
Spot ether ETFs followed the same path, with about $542 million of outflows over the week, according to TokenPost.
The picture improved at the start of the following week. Crypto Briefing reports that US spot bitcoin ETFs took in $175.6 million on 13 October, led by $103.1 million into Fidelity’s FBTC. Over the 30 days to 13 October, the funds still recorded about $2.06 billion of net inflows.
Why bitcoin and the ETFs came under pressure
The trigger was macroeconomic rather than specific to crypto. On 8 October, Yahoo Finance linked the drop in crypto prices to persistent inflation concerns, fuelled by the conflict in the Middle East that pushed oil sharply higher, with Brent crude futures above $105 a barrel that morning. Bitcoin opened that day 2.7% below its level of the previous morning and about 31% below its level a year earlier, according to the same data.
Higher energy prices feed into inflation, which can keep interest rates high for longer. That tends to weigh on assets with no yield, such as bitcoin, and on the appetite of institutional investors who use ETFs.
Vikram Subburaj, chief executive of the Indian exchange Giottus, told CoinDesk that “ETF flows remain volatile”, adding that the heavy outflows of 7 and 8 October signalled cautious institutional sentiment.
Markets stayed choppy after the weekly close. Bitcoin rebounded early on Monday 12 October before giving back part of the gain as oil recovered, CoinDesk reported. Crude had dipped after President Donald Trump announced on Friday an agreement for Russia to supply 300,000 metric tons of diesel, a partial easing of US sanctions on Russian oil. Other large cryptocurrencies moved in the same direction as bitcoin over the period.
How big are the bitcoin ETFs?
The weekly outflow is small next to the size of the market. Crypto Briefing puts total net assets of US spot bitcoin ETFs at about $100.75 billion and cumulative net inflows at $57.68 billion since their launch in January 2024, as of 13 October. That is roughly 6% of bitcoin’s market capitalisation, by the same source’s estimate.

What it means for investors
Daily ETF flows are a useful gauge of institutional demand, but they swing quickly: a week of heavy outflows was followed within days by a sizeable inflow. Short-term moves in flows say little about long-term direction. Some savers smooth these swings with dollar-cost averaging, buying fixed amounts at regular intervals; that limits timing risk but does not remove the risk of loss.
